Cannot find new s3 bucket

There are a few potential reasons why you might not be able to find your S3 bucket named Credenza:

1. Account mismatch: Ensure you're signed in to the correct AWS account where you originally created the bucket. S3 bucket names are globally unique across all AWS accounts, so if you can't create a new bucket with the same name, it likely exists in some account.

2. Region visibility: Unlike some AWS services, S3 buckets are visible in the S3 console regardless of the region they were created in. You should be able to see all your buckets in any region's S3 console view.

3. Permissions issue: Check that your IAM user or role has the necessary permissions to list and view S3 buckets.

4. CloudTrail logs: If you have CloudTrail enabled, you can search for the "CreateBucket" API call around the time you believe you created the bucket. This can help confirm the creation and potentially show which account or user created it.

5. AWS CLI: As an alternative to the console, you can try listing your buckets using the AWS Command Line Interface (CLI) with the command: aws s3 ls

6. Recent deletion: If you or someone else recently deleted the bucket, the name might still be unavailable for reuse. It can take some time before a deleted bucket's name becomes available again.

If you still can't locate the bucket after these checks, it's advisable to contact AWS Support for further assistance, as they can provide more detailed information about your account's resources.
